Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - copy IV using skcipher ivsize AF_ALG rfc3686-ctr-aes-ccp requests pass an 8-byte IV to the driver. ccp_aes_complete() restores AES_BLOCK_SIZE bytes into the caller's IV buffer while RFC3686 skciphers expose an 8-byte IV, so the restore overruns the provided buffer. Use crypto_skcipher_ivsize() to copy only the algorithm's IV length.

No race or condition outside the attacker\u0027s control is required.\nPR:L - AF_ALG socket creation, bind, key setup, accept, sendmsg, and recvmsg have no capability checks, so a basic unprivileged local user can reach the bug. The driver-only flag can be selected through the allowed AF_ALG feature/mask fields.\nUI:N - Exploitation is entirely driven by the attacker\u0027s local syscalls. No separate victim action is required.\nS:U - The vulnerability corrupts kernel memory within the same kernel security authority. It does not cross a VM, IOMMU, or similar security boundary.\nC:H - The bug is an attacker-reachable kernel heap out-of-bounds write caused by copying 16 IV bytes into an 8-byte AF_ALG IV buffer. Kernel memory corruption can reasonably be developed into information disclosure primitives.\nI:H - The overwrite corrupts adjacent kernel heap memory from an unprivileged request path. As an out-of-bounds write, it is defensibly scored as potentially enabling arbitrary memory modification or control-flow compromise.\nA:H - Even without full exploitation, the heap corruption can crash or destabilize the kernel. Repeated unprivileged triggering can therefore cause high availability impact."
